No real direct disadvantages, you will fill your database quicker than most, but storage is cheap and it's nothing that the dbms used by weeWX can't handle. CPU load is not necessarily an issue, unless you make it an issue. WeeWX spends most of its time reading and storing loop data and doing other bits of housekeeping, all not very CPU intensive. The CPU intensive work happens during the report generation, depending on your machine the report cycle might take a few seconds, a tens of seconds or longer. If you add extra reports to your system and your reports (regularly) take longer than your archive period to run then the next report cycle kicks off before the last one finishes. Because report generation is CPU intensive it slows down the already running reports. So as you can imagine things can slowly grind to a halt. Now if your archive period is short, and if you have added more reports, you have more chance of running into this overload situation than someone who, say, uses a 5 minute archive period. If you like, you have less 'headroom'. Also coming into the equation are any other tasks your macine is doing (web server etc) as they will load the system as well.
At the end of the day it really is horses for courses. If your reports(including FTP) take a few seconds to run you can probably handle 1minute easily. If your reports take say 45+ seconds you are probably borderline, anything more and you are asking for trouble. You will find lots of folks use a 5 minute archive period with a Vantage. Get your system running as you want then monitor your logs for a few cycles to see how long the reports take. If you add more reports to your system, monitor your logs again. One final thing, if you start using 1 minute and decide later to move to 5 minutes (or vice versa), there is no simple method to move between the two. It can be done but you will need to manually manipulate your database. Gary -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
